This invention relates to a new aluminosilicate zeolite designated UZM-50 and its use as a catalyst in hydrocarbon conversion processes. This zeolite is represented by the empirical formula: M⁺ _(m)R_(r)Al_(1−x)E_(x)Si_(y)O_(z) where M is selected from the group consisting of hydrogen, sodium, potassium, magnesium, calcium or combinations thereof, R is the organic structure directing agent or agents derived from reactants R1 and R2 where R1 is an amine essentially incapable of undergoing pyramidal inversion and having 7 or fewer carbon atoms, and R2 is a dihaloalkane, and E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof.

BACKGROUND OF THE INVENTION

Zeolites are crystalline aluminosilicate compositions which are microporous and which are formed from corner sharing AlO₂ and SiO₂ tetrahedra. Numerous zeolites, both naturally occurring and synthetically prepared, are used in various industrial processes. Synthetic zeolites are prepared via hydrothermal synthesis employing suitable sources of Si, Al and structure directing agents such as alkali metals, alkaline earth metals, amines, or organoammonium cations. The structure directing agents reside in the pores of the zeolite and are largely responsible for the particular structure that is ultimately formed. These species balance the framework charge associated with aluminum and can also serve as space fillers. Zeolites are characterized by having pore openings of uniform dimensions, having a significant ion exchange capacity, and being capable of reversibly desorbing an adsorbed phase which is dispersed throughout the internal voids of the crystal without significantly displacing any atoms which make up the permanent zeolite crystal structure. Zeolites can be used as catalysts for hydrocarbon conversion reactions, which can take place on outside surfaces as well as on internal surfaces within the pore.

As used herein, zeolites may be referred to by improper name, such as beta, proper name, such as CIT-6, or by structure type code, such as *BEA. These three letter codes indicate atomic connectivity and hence pore size, shape and connectivity for the various known zeolites. The list of these codes may be found in the Atlas of Zeolite Framework Types, which is maintained by the International Zeolite Association Structure Commission at http://www.iza-structure.org/databases/. At present, 234 structure types are known and catalogued by the IZA. One such structure type, *BEA has been described in the literature and is known to contain 3-dimensional 12-ring channels. Zeolites are distinguished from each other on the basis of their composition, crystal structure, and adsorption properties. One method commonly used in the art to distinguish zeolites is x-ray diffraction. A newer x-ray method is small angle x-ray scattering, SAXS.

Beta zeolite was first described structurally in the literature by Higgins, et al. in Zeolites, 1988, 8, 446-52. Using tetraethylammonium as the cationic organic structure directing agent (OSDA), they crystallized a material having a powder x-ray diffraction pattern containing a combination of sharp and broad reflections at SiO₂/Al₂O₃ ratios in the range of 30-50. They identified disorder along the [001] direction and proposed three polymorphs of the beta zeolite, A, B, and C. These three polymorphs are constructed from the same layer but with different shifts along the a or b axes. Beta zeolite has at least peaks in the x-ray diffraction pattern at 7.5, 13.44, 21.38, and 22.43°2θ using Cu—Kα radiation.

Corma and coworkers (Chem. Mater. 2008, 20, 3218-23) synthesized materials significantly enriched in polymorph B using 4,4-dimethyl-4-azoniatricyclo[5.2.2.0]undec-8-ene as the OSDA. This material has an x-ray diffraction pattern with peaks at positions of at least 7.5, 8.2, 13.5, 21.4, and 22.4°2θ using Cu—Kα radiation.

Polymorph C has been synthesized by Moliner, et al., using 4,4-dimethyl-4-azoniatricyclo[5.2.2.0]undec-8-ene as the OSDA. This polymorph has been given the structure code BEC. The ITQ-17 material so produced (J. Phys. Chem. C 2008, 112, 19547-54) comprises titanium and has an x-ray diffraction pattern with peaks at positions of at least 6.9, 9.6, 15.3, 19.2, and 22.2°2θ using Cu—Kα radiation.

In addition to the A, B, and C polymorphs, two additional polymorphs of the beta zeolite system have been synthesized and named SU-78A and SU-78B. Yu, et al., described the SU-78 material synthesized using either N,N-dimethyl-dicyclohexylammonium or N-ethyl-N-methyl-dicyclohexylammonium as the OSDA in Chem. Mater. 2012, 24, 3701-6 as an intergrowth with complex twinning and disorder of the SU-78A and SU-78B polymorphs. These materials comprise germanium and have an x-ray diffraction pattern with at least 9 peaks using Cu—Kα radiation.

Takewaki, et al., discovered the CIT-6 family of materials (J. Phys. Chem. B 1999, 103, 2674-2679) as a composition comprising zinc which can be extracted in various post-synthesis treatments. These materials are of the disordered *BEA type and have an x-ray diffraction pattern with at least 6 peaks using Cu—Kα radiation.

A naturally occurring mineral version of beta zeolite is also known, called tschernichite. Tschernichite usually comprises calcium and has SiO₂/Al₂O₃ ratios in the range of 3-8 and a powder x-ray diffraction pattern containing a combination of sharp and broad reflections. The x-ray diffraction pattern comprises peaks at d-spacings of at least approximately 11.6-12, 6.3, 4.21, 4.02, 3.56, and 3.15 Å using Cu—Kα radiation.

Zeolite beta is of the disordered *BEA zeotype and known to be heavily faulted. A typical preparation comprises about 60% polymorph A and 40% polymorph B with typical ratios of the polymorphs varying by 10-20% according to preparation (Cantin, et al., Angew. Chem. Int. Ed. 2006, 45, 8013-15). Materials comprising intergrowths of the A and B polymorphs are included in the partially disordered material code *BEA. Szostak and coworkers show in J. Phys. Chem. 1995, 99, 2104-9 that tschernichite is also an intergrowth of the A and B polymorphs at about the same ratios.

Many materials described in the literature as nanocrystalline beta zeolites are also known. These include materials synthesized by Mihailova, et al., (Phys. Chem. Phys. Chem. 2005, 7, 2756-63), Ding and Zheng (Mater. Res. Bull. 2007, 42, 584-90), Casci and coworkers (NU-2, Stud. Surf. Sci. Catal. 1989, 49A, 151-160), Perez-Pariente, et al., (Appl. Catal. 1987, 31, 35-64), Kobler, et al., (J. Phys. Chem. C 2008, 112, 14274-80), Larlus, et al., (Micro. Meso. Mater. 2011, 142, 17-25) and Keuchl, et al., (Micro. Meso. Mater. 2010, 127, 104-18). Numerous other zeolites, including other zeolites of the *BEA type, are known.

DETAILED DESCRIPTION OF THE INVENTION

Applicants have prepared a new aluminosilicate zeolite designated as UZM-50. As will be shown in detail, UZM-50 is different from known zeolites in a number of its characteristics, and it finds utility as a catalyst in hydrocarbon conversion processes. The UZM-50 materials are differentiable from other known zeolites, possessing different x-ray diffraction patterns, elemental compositions, Na micropore volumes, Na mesopore volumes, SAXS features, crystallite sizes, IR or Raman spectroscopic signatures, H₂O adsorption capacities, or combinations thereof.

UZM-50 is a microporous crystalline zeolite having a three-dimensional framework of at least AlO₂ and SiO₂ tetrahedral units and a composition in an as synthesized and anhydrous basis expressed by an empirical formula of: M⁺ _(m)R_(r)Al_(1−x)E_(x)Si_(y)O_(z) where M is selected from the group consisting of hydrogen, sodium, potassium, magnesium, calcium and combinations thereof, “m” is the mole ratio of M to (Al+E) and varies from 0 to about 1, R is the organic structure directing agent or agents derived from reactants R1 and R2 where R1 is an amine essentially incapable of undergoing pyramidal inversion and having 7 or fewer carbon atoms, and R2 is a dihaloalkane, “r” is the mole ratio of nitrogen from the organic structure directing agent or agents to (Al+E) and has a value of from about 0.2 to about 4, E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof, “x” is the mole fraction of E and has a value from 0 to about 1.0, “y” is the mole ratio of Si to (Al+E) and varies from greater than 5 to about 60 and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation: z=(m+3+4•y)/2. UZM-50 may be characterized in that an average diameter of the smallest feature observed by SAXS is less than 12 nm, it has a ratio of a N₂ mesopore volume to total pore volume≥0.85, and it has the x-ray diffraction pattern having at least the d-spacing's and intensities set forth in Table A:

TABLE A 2θ d (Å) I/I₀ % ~7.5 11.5-11.9 S ~22.4 3.92-3.99 VS

In an aspect, M is selected from the group consisting of hydrogen, sodium, potassium, and combinations thereof.

In an aspect, m is greater than about 0.05, or is greater than about 0.1, or is less than about 0.5, or is less than about 0.4. In an aspect, x is greater than about 0.05, or is less than about 0.75, or is less than about 0.5, or is less than about 0.4. In an aspect, y is greater than about 6, or is greater than about 7, or is greater than about 8, or is less than about 50, or is less than about 40, or is less than about 30.

R is the organic structure directing agent or agents derived from reactants R1 and R2 where R1 is at least one neutral monoamine having 7 or fewer carbon atoms and R2 is a dihalogen substituted alkane having between 3 and 6 carbon atoms. In an aspect, r is greater than about 0.25, or is greater than about 0.3, or is less than about 3, or is less than about 2.5.

In an aspect, the substituted alkane R2 is a dihalogen substituted alkane having from 3 to 6 carbon atoms selected from the group consisting of 1,2-di-halo-propane, 1,3-di-halo-butane, 1,3-di-halo-pentane, 1,4-di-halo-pentane, 2,4-di-halo-pentane, 1,5-di-halo-hexane, 1,4-di-halo-hexane, 1,3-di-halo-hexane, 2,4-di-halo-hexane, and 2,5-di-halo-hexane. In an aspect, R2 has 5 or 6 carbon atoms.

R2 may be an A,Ω-dihalogen substituted alkane having between 3 and 6 carbon atoms selected from the group consisting of 1,3-dichloropropane, 1,4-dichlorobutane, 1,5-dichloropentane, 1,6-dichlorohexane, 1,3-dibromopropane, 1,4-dibromobutane, 1,5-dibromopentane, 1,6-dibromohexane, 1,3-diiodopropane, 1,4-diiodobutane, 1,5-diiodopentane, 1,6-diiodohexane and combinations thereof.

R1 comprises at least one tertiary monoamine being essentially incapable of undergoing pyramidal inversion and having 7 or fewer carbon atoms. R1 may comprise combinations of multiple neutral monoamines having 7 or fewer carbon atoms.

Suitable amines include those for which at least one conformer is essentially incapable of undergoing pyramidal inversion. The IUPAC definition of pyramidal inversion is given as, “a polytopal rearrangement in which the change in bond directions to a three-coordinate central atom having a pyramidal arrangement of bonds (tripodal arrangement) causes the central atom (apex of the pyramid) to appear to move to an equivalent position on the other side of the base of the pyramid. If the three ligands to the central atom are different pyramidal inversion interconverts enantiomers.” The tripodal nature of many nitrogen compounds results in the ability of these compounds to undergo pyramidal inversion. Typically, the energy barrier to inversion is low for unconstrained molecules. For example, ammonia (NH₃) has an inversion barrier of 24.5 kJ mol⁻¹, with an observed inversion frequency of about 2.4*10¹⁰ s⁻¹, dimethylamine has an inversion barrier of 18 kJ mol⁻¹, triisopropylamine has an inversion barrier of 6-8 kJ mol⁻¹ and dimethylethylamine has an inversion barrier of 22 kJ mol⁻¹. However, inversion barrier energy can become very high when the nitrogen substituents are part of a small ring or other rigid molecule as in the case of 1-methylpyrrolidine. Molecules defined as essentially incapable of undergoing pyramidal inversion have an inversion barrier energy of at least about 28 kJ mol⁻¹, or at least about 30 kJ mol⁻¹. A discussion of pyramidal inversion may be found in Rauk, A., et al., (1970), Pyramidal Inversion. Angew. Chem. Int. Ed. Engl., 9: 400-414, with further discussion specifically for amines found in “Inorganic Chemistry” edited by Arnold F. Holleman, et al., Academic Press, 2001. Molecules may exist in many conformers or folding patterns. For example, it is well known that both chair and boat forms of cyclohexane exist and interconvert between the two different conformers. In an aspect of the invention, at least one conformer of the amine is essentially incapable of undergoing pyramidal inversion.

Table 1 provides examples of molecules essentially incapable of undergoing pyramidal inversion.

This invention relates to a process for preparing crystalline aluminosilicate UZM-50 compositions including quaternary ammonium salts. Preferentially, the process comprises a process for preparing quaternary ammonium salts. The process may involve first forming an aqueous phase solution of a quaternary ammonium salt from suitable reagents such as a di-substituted alkane and an amine. The pre-reacted quaternary ammonium salt solution may then be incorporated into a zeolite reaction mixture containing sources of aluminum, silicon, and optionally other reagents, and the resultant mixture reacted at a temperature and for a time to crystallize the aluminosilicate UZM-50 composition. Alternatively, the quaternary ammonium salts may be synthesized by other methods known in the art and incorporated into the reaction mixture.

In one aspect, the invention provides a method for synthesizing a zeolite. The method comprises first forming a reaction mixture including reactive sources of Al, Si, R, optionally M and/or E, and then heating the reaction mixture to form the zeolite.

The reaction mixture may be heated at a temperature of about 125° C. to about 185° C. for a time of about 1 day to about 3 weeks in a sealed reaction vessel under autogenous pressure. After crystallization is complete, the solid product is isolated from the heterogeneous mixture by means such as filtration or centrifugation, and then washed with deionized water and dried in air at ambient temperature up to about 100° C. The reaction mixture may be heated at a temperature of about 135° C. to about 175° C. for a time of about 1 day to about 3 weeks. In an embodiment, the reaction mixture is heated at a temperature of about 165° C. to about 175° C. for a time of about 1 day to about 1 week. Prior to the heating step, an aging step may be performed at a temperature of about 85° C. to about 125° C. for a time of about 4 hours to about 5 days in a sealed reaction vessel under autogenous pressure.

In some embodiments, the reactive source of R is a solution comprising an organoammonium product formed by the method comprising: (a) preparing an aqueous mixture comprising water, a substituted hydrocarbon, and an amine other than trimethylamine wherein the amine is a tertiary amine having 7 or less carbon atoms and being essentially incapable of undergoing pyramidal inversion, or combinations thereof; (b) reacting the aqueous mixture; and (c) obtaining a solution comprising an organoammonium product. In one version of the method, the step of reacting the aqueous mixture occurs at a temperature between 20° C. and 100° C. In another version of the method, the organoammonium product comprises a structure directing agent R.

In an aspect, R may comprise 1,5-bismethylpyrrolidinium pentane dihydroxide, or 1,5-bisethylpyrrolidinium pentane dihydroxide, or 1,5-bismethylpiperidinium pentane dihydroxide, or 1,5-bisethylpiperidinium pentane dihydroxide, or 1,5-bismethylmorpholinium pentane dihydroxide, or 1,5-bisethylmorpholinium pentane dihydroxide. R may comprise 1,4-bismethylpyrrolidinium butane dihydroxide, or 1,4-bisethylpyrrolidinium butane dihydroxide, or 1,4-bismethylpiperidinium butane dihydroxide, or 1,4-bisethylpiperidinium butane dihydroxide, or 1,4-bismethylmorpholinium butane dihydroxide, or 1,4-bisethylmorpholinium butane dihydroxide. R may comprise 1,6-bismethylpyrrolidinium hexane dihydroxide, or 1,6-bisethylpyrrolidinium hexane dihydroxide, or 1,6-bismethylpiperidinium hexane dihydroxide, or 1,6-bisethylpiperidinium hexane dihydroxide, or 1,6-bismethylmorpholinium hexane dihydroxide, or 1,6-bisethylmorpholinium hexane dihydroxide.

UZM-50, in the as-synthesized and anhydrous basis, is characterized by the x-ray diffraction pattern, having at least the d-spacings and relative intensities set forth in Table A below. Additional peaks, particularly those of very weak intensity, may also be present. All peaks of medium or higher intensity present in UZM-50 are represented in Table A. Diffraction patterns herein were obtained using a typical laboratory powder diffractometer, utilizing the K_(α) line of copper; Cu K alpha. From the position of the diffraction peaks represented by the angle 2 theta, the characteristic interplanar distances d_(hkl) of the sample can be calculated using the Bragg equation. The intensity is calculated on the basis of a relative intensity scale attributing a value of 100 to the line representing the strongest peak on the X-ray diffraction pattern, and then: weak (W) means less than 12; medium (M) means in the range 12 to 25; strong (S) means in the range 25 to 65; very strong (VS) means more than 65. Intensities may also be shown as inclusive ranges of the above. The X-ray diffraction patterns from which the data (d spacing and intensity) are obtained are characterized by a large number of reflections some of which are broad peaks or peaks which form shoulders on peaks of higher intensity. Some or all of the shoulders may not be resolved. This may be the case for samples of low crystallinity, of particular morphological structures or for samples with crystals which are small enough to cause significant broadening of the X-rays. This can also be the case when the equipment or operating conditions used to produce the diffraction pattern differ significantly from those used in the present case.

UZM-50 is a microporous crystalline zeolite having a three-dimensional framework of at least AlO₂ and SiO₂ tetrahedral units and a composition in an after calcination and on an anhydrous basis expressed by an empirical formula of: M1⁺ _(m1)Al_(1−x)E_(x)Si_(y)O_(z) where M1 represents hydrogen, sodium, potassium, magnesium, calcium, ammonium, or combinations thereof, and E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof, and is characterized in that an average diameter of the smallest feature observed by SAXS is less than 12 nm, it has a ratio of a N₂ mesopore volume to total pore volume≥0.85, and it has the x-ray diffraction pattern having at least the d-spacing's and intensities set forth in Table B:

TABLE B 2θ d (Å) I/I₀ % ~7.5 11.5-11.9 VS ~22.4 3.93-3.98 VS

The values of m1, x, y, and z are as described above for the as synthesized version (with m1 having the same values as m).

As will be shown in detail in the examples, the UZM-50 material is thermally stable up to a temperature of at least 600° C., and in another embodiment, up to at least 800° C. Also as shown in the examples and in an aspect, the UZM-50 material may have a mesopore volume as a percentage of total pore volume of greater than 88%, or greater than 90%, or greater than 92% as determined by BET analysis using N₂. In an aspect, the UZM-50 material may have a mesopore volume as a percentage of total pore volume of less than 100%, or less than 98%, or less than 95% as determined by BET analysis using N₂. In an aspect, the UZM-50 may have a micropore volume of greater than about 0.145 mL/g, or greater than about 0.150 mL/g, or greater than about 0.155 mL/g, or less than about 0.200 mL/g, or less than about 0.192 mL/g, or less than about 0.187 mL/g as determined by BET analysis using N₂.

As synthesized, the UZM-50 material will contain some exchangeable or charge balancing cations in its pores. These exchangeable cations can be exchanged for other cations, or in the case of organic structure directing agents (SDAs), they can be removed by heating under controlled conditions. It may be possible to remove some organic SDAs from the UZM-50 zeolite directly by ion exchange. The UZM-50 zeolite may be modified in many ways to tailor it for use in a particular application. Modifications include calcination, ion-exchange, steaming, various acid extractions, ammonium hexafluorosilicate treatment, or any combination thereof, as outlined for the case of UZM-4M in U.S. Pat. No. 6,776,975 B1 which is incorporated by reference in its entirety. Conditions may be more severe than shown in U.S. Pat. No. 6,776,975. Properties that are modified include porosity, adsorption, Si/Al ratio, acidity, thermal stability, and the like.

After calcination and on an anhydrous basis, the microporous crystalline zeolite UZM-50 displays the XRD pattern shown in Table B. Those peaks characteristic of UZM-50 are shown in Table B. Additional peaks, particularly those of very weak intensity, may also be present. All peaks of medium or higher intensity present in UZM-50 are represented in Table B.

TABLE B 2θ d (Å) I/I₀ % ~7.5 11.5-11.9 VS ~22.4 3.93-3.98 VS

In an embodiment, two peaks of strong intensity or greater are present. In an embodiment, fewer than 4 peaks of strong intensity or greater are present. In an embodiment, fewer than 3 peaks of strong intensity or greater are present. In an embodiment, only two peaks of very strong intensity are present.

The characteristic full width at half maximum (FWHM) of the UZM-50 or comparative materials may be determined on the basis of the X-ray diffraction pattern of the material using a linear background. This may be most readily accomplished by peak fitting routines known to one skilled in the art, such as those implemented in JADE software available from MDI, but may also be determined via more manual methods. For UZM-50 materials, the FWHM of Peak 1 is the full width (in terms of 2θ) of the peak at 2θ≈7.5° (±0.5°) at half the maximum height of the peak. For UZM-50 materials, the FWHM of Peak 2 is the full width (in terms of 2θ) of the peak at 2θ≈22.4° (±0.5°) at half the maximum height of the peak. The Peak 1 FWHM of UZM-50 may be greater than about 1.25, or may be greater than 1.28, or may be greater than 1.29, or may be greater than 1.30, or may be greater than 1.32. In an aspect, the Peak 1 FWHM of UZM-50 may be less than 2.00, or may be less than 1.75, or may be less than 1.60. The Peak 2 FWHM of UZM-50 may be greater than about 0.80, or may be greater than 0.90, or may be greater than 0.95, or may be greater than 1.00, or may be greater than 1.05. In an aspect, the Peak 2 FWHM of UZM-50 may be less than 2.00, or may be less than 1.75, or may be less than 1.60.

The distance between Peak 1 of UZM-50 and Peak 2 of UZM-50 may be characteristic. An InterPeak distance (in terms of 2θ) may be determined by subtracting the degrees 20 of Peak 1 from that of Peak 2. In an aspect, the InterPeak distance of UZM-50 (using copper source of wavelength: 1.5418 angstroms) may be greater than 14.75°2θ, or may be greater than 14.78, or may be greater than 14.80, or may be greater than 14.85. In an aspect, the InterPeak distance of UZM-50 may be less than 15.25, or may be less than 15.20, or may be less than 15.15. Table 2 shows characteristics of UZM-50 example materials determined by XRD analysis.

For the determination of the X-ray diffraction pattern, a standard powder diffractometer (e.g., Rigaku Ultima IV) equipped with a graphite monochromator may be used. One skilled in the art understands the basic method of utilizing powder XRD to obtain a diffraction pattern. The measurement conditions may, e.g., be chosen as follows: X-ray generator settings: 40 kV and 44 mA; wavelength: 1.5418 angstroms; divergence and anti-scatter slits: 2/3°; detector slit: 0.3 mm; step size: 0.02 (° 2θ); time/step: 1 seconds.

In specifying the proportions of the zeolite starting material or adsorption properties of the zeolite product and the like herein, the “anhydrous state” of the zeolite will be intended unless otherwise stated. The term “anhydrous state” is employed herein to refer to a zeolite substantially devoid of both physically adsorbed and chemically adsorbed water.

The crystalline UZM-50 zeolite of this invention can be used for separating mixtures of molecular species, removing contaminants through ion exchange and catalyzing various hydrocarbon conversion processes. Separation of molecular species can be based either on the molecular size (kinetic diameter) or on the degree of polarity of the molecular species. The separation process may comprise contacting at least two components with the UZM-50 zeolite material to generate at least one separated component.

The UZM-50 zeolite of this invention can also be used as a catalyst or catalyst support in various hydrocarbon conversion processes. The catalyst may contain from about 0 wt % to about 100 wt % of the UZM-50 zeolite, or about 10 wt % to about 100 wt %, or about 20 wt % to about 100 wt %, or about 30 wt % to about 100 wt %, or about 40 wt % to about 100 wt %, or about 50 wt % to about 100 wt %, or about 60 wt % to about 100 wt %, or about 70 wt % to about 100 wt %, or about 80 wt % to about 100 wt %, or about 90 wt % to about 100 wt %, or about 0 wt % to about 90 wt %, or about 0 wt % to about 80 wt %, or about 0 wt % to about 70 wt %, or about 0 wt % to about 60 wt %, or about 0 wt % to about 50 wt %, or about 0 wt % to about 40 wt %, or about 0 wt % to about 30 wt %, or about 0 wt % to about 20 wt %, or about 0 wt % to about 10 wt %.

Hydrocarbon conversion processes are well known in the art and include oligomerization, hydrocracking, hydroisomerization, hydrotreating, hydrodenitrogenation, hydrodesulfurization, naphthene ring opening, paraffin isomerization, olefin isomerization, conversion of an aromatic molecule to another aromatic molecule, polyalkylbenzene isomerization, disproportionation of alkylbenzenes, aromatic alkylation, paraffin alkylation, paraffin cracking, naphthene cracking, reforming, hydrogenation, dehydrogenation, transalkylation, dealkylation, hydration, and dehydration.

Using a UZM-50 catalyst composition which contains a hydrogenation promoter such as platinum or palladium, heavy petroleum residual stocks, cyclic stocks and other hydrocrackable charge stocks may be hydrocracked at temperatures in the range of about 204° C. to about 649° C. (400° to 1200° F.) or about 316° C. to about 510° C. (600° F. and 950° F.). Nickel, cobalt, molybdenum and tungsten are additionally known in the art as hydrogenation promoters.

Reaction pressures are in the range of atmospheric to about 24,132 kPa g (3,500 psig), or between about 1379 to about 20,685 kPa g (200 to 3000 psig). Contact times usually correspond to liquid hourly space velocities (LHSV) in the range of about 0.1 hr⁻¹ to 15 hr⁻¹, or between about 0.2 and 10 hr⁻¹. Hydrogen circulation rates are in the range of 178 to about 8,888 std. m³/m³ (1,000 to 50,000 standard cubic feet (scf) per barrel of charge), or about 355 to about 5,333 std. m³/m³ (about 2,000 to about 30,000 scf per barrel of charge). Suitable hydrotreating conditions are generally within the broad ranges of hydrocracking conditions set out above.

These same catalysts, i.e. those containing hydrogenation promoters, may also be useful in hydroisomerization processes in which feedstocks such as normal paraffins are converted to saturated branched chain isomers. Hydroisomerization is carried out at a temperature of from about 93° C. to about 450° C. (200° F. to 842° F.), or about 150° C. to about 300° C. (300° F. to 572° F.) with an LHSV value of from about 0.2 to 1.0. Hydrogen is supplied to the reactor in admixture with the hydrocarbon feedstock in molar proportions (H₂/HC) of between 1 and 5.

Catalytic cracking processes may be preferably carried out with the UZM-50 composition using feedstocks such as gas oils, heavy naphthas, deasphalted crude oil residua, etc. with gasoline being the principal desired product. Temperature conditions of about 454° C. to about 593° C. (about 850° F. to about 1100° F.), LHSV values of 0.5 to 10 and pressure conditions of from about 0 to about 344 kPa g (about 0 to 50 psig) are suitable.

Alkylation of aromatics usually involves reacting an aromatic (C₂ to C₁₂), especially benzene, with a monoolefin to produce a linear alkyl substituted aromatic. The process may be carried out at an aromatic: olefin (e.g., benzene:olefin) ratio of between 1:1 and 30:1, a olefin LHSV of about 0.3 to about 10 hr⁻¹, a temperature of about 100° to about 250° C. and pressures of about 1379 kPa g to about 6895 kPa g (about 200 to about 1000 psig). Further details on apparatus may be found in U.S. Pat. No. 4,870,222 which is incorporated by reference.

Alkylation of isoparaffins with olefins to produce alkylates suitable as motor fuel components may be carried out at temperatures of −30° to 40° C., pressures from about atmospheric to about 6,895 kPa (1,000 psig) and a weight hourly space velocity (WHSV) of 0.1 to about 120. Details on paraffin alkylation may be found in U.S. Pat. Nos. 5,157,196 and 5,157,197, which are incorporated by reference.

Isomerization reactions are carried out under conditions identified for the feedstock. Olefins may be preferably isomerized at temperatures of about 150° C. to about 500° C. (302° F.-932° F.), while paraffins, naphthenes and alkyl aromatics are isomerized at temperatures of from about 350° C. to about 550° C. (662° F.-1022° F.). Particularly desirable isomerization reactions contemplated herein include the conversion of n-heptane and/or n-octane to isoheptanes, iso-octanes, butane and iso-butane, methylcyclopentane to cyclohexane, meta-xylene and/or ortho-xylene to paraxylene, 1-butene to 2-butene and/or isobutene, n-hexene to iso-hexene, cyclohexene to methylcyclopentene etc.

Catalyst compositions comprising UZM-50 may be useful for the oligomerization of olefins to longer olefins such as gasoline and distillate range olefins. Light olefins such as ethene, propene, butene and pentenes may be oligomerized to gasoline or distillate range olefins. Liquid phase operation is typically preferred. Operating pressures may include between about 2.1 MPa (300 psia) and about 10.5 MPa (1520 psia), but other pressures are contemplated depending on feed and recycle such that liquid phase is maintained. With liquid oligomerate recycle, lower pressures are often possible to maintain liquid phase. Temperature may be in a range between about 100° C. and about 350° C. or may be between about 180° C. and about 300° C. The weight hourly space velocity may be between about 0.5 and about 10 hr⁻¹. Additional conditions for successful operation may be given in U.S. Pat. No. 9,278,893, hereby incorporated by reference.

Catalyst compositions comprising UZM-50 may be useful for the conversion of an aromatic molecule to another aromatic molecule. The conversion of an aromatic molecule may involve reacting an aromatic feed molecule (C₆ to C₁₂) over a catalyst comprising UZM-50 to form a product comprising another aromatic molecule. The product aromatic molecule may be of the same, higher, or lower molecular weight than the feed aromatic molecule. The process may be carried out at a WHSV of about 0.1 to about 100 hr⁻¹, a temperature of about 50° C. to about 750° C. and pressures of about 101 kPa g to about 20265 kPa g (about 1 atm to about 200 atm). In an aspect, the aromatic molecule feed is selected from the group of benzene, toluene, p-xylene, m-xylene, o-xylene, and combinations thereof. In an aspect, the process is carried out at a WHSV of from about 0.1 to about 10 hr⁻¹. In an aspect, the process is carried out at a temperature of about 100° C. to about 500° C. In an aspect, the process may be carried out at a pressure of no greater than about 10132 kPa g (100 atm). In an aspect, the aromatic molecule product is selected from the group of benzene, toluene, p-xylene, m-xylene, o-xylene, and combinations thereof.

By about, we mean within 10% of the value, or within 5% of the value, or within 1% of the value.

The invention will now be further illustrated by the following non-limiting examples.

EXAMPLES Example 1

852.4 g deionized water was weighed into a 2 L Teflon bottle. The bottle was placed into a 4 L beaker, a stir bar was added, and stirring on a magnetic stir plate was started. 489.7 g 1,5 Dibromopentane, 97% was added. Then 362.7 g 1-Methylpyrrolidine, 97% was added. About 1.5 L water (room temperature (RT)) was placed between the bottle and beaker to help disperse any exotherm. This was allowed to mix overnight. 1697 g of yellow solution was recovered.

Example 2

874.8 g deionized water was weighed into a 2 L Teflon bottle. The bottle was placed into a 4 L beaker, a stir bar was added, and stirring on a magnetic stir plate was started. 474.1 g 1,5 dibromopentane (DBP), 97% was added. Then 400.7 g 1-Methylpiperidine, 99% was added. About 1.5 L water (RT) was placed between the bottle and beaker to help disperse any exotherm. This was allowed to mix overnight. There was no visible vortex in the morning, so the stirring was insufficient. A Heidolph high speed mixer was used to stir the mixture all day. This slowly turned into a yellow solution. The mixing was stopped for about 52 hours and was then resumed for a further 8 hours. A yellow solution resulted with some clear unreacted DBP on the bottom which was separated out. Analysis showed the yellow solution to be 49.5% water.

Example 3

1000 g of Example 1 product was loaded into a 3-necked round bottom flask with overhead stirring. 295.4 g Ag₂O, 99% was added, and the flask was covered with aluminum foil. It was mixed for 48 hours at room temperature. Glass filters were used to isolate a clear yellow solution. The solution was filtered a few times over the next week or two. Analysis showed this solution to be 65.5% water.

Example 4

1100 g of Example 2 product was loaded into a 3-necked round bottom flask with overhead stirring. 303.6 g Ag₂O was added, and the flask was covered with aluminum foil. It was mixed for 48 hours at room temperature. Glass filters were used to isolate a clear yellow solution. The solution was filtered a few times over the next week or two. Analysis showed this solution to be 64.5% water.

Example 5

6.47 g aluminum hydroxide (Pfaltz&Bauer) was stirred into 213.0 g of Example 3 product. When it became a solution, 200 g Ludox AS-40 colloidal silica was added. To this mixture, 196.9 g deionized water was added, and the resulting mixture was placed in a 100° C. oven overnight in a sealed Teflon bottle. In the morning, this was found to be a soft gel. The gel was cooled, and 196.9 g water was added before the mixture was re-slurried for use. ICP (inductively coupled plasma) analysis shows the slurry consists of 4.82% Si and 0.24% Al.

Example 6

6.47 g aluminum hydroxide (Pfaltz&Bauer) was stirred into 228.14 g of Example 4 product. When it became a solution, 200 g Ludox AS-40 was added. To this mixture, 202.6 g deionized water was added, and the resulting mixture was placed in a 100° C. oven overnight in a sealed Teflon bottle. In the morning, this was found to be a soft gel. The gel was cooled, and 202.6 g water added before the mixture was re-slurried for use.

Example 7

The Example 5 mixture was loaded into 45 cc Parr bombs. Some were digested statically, while others were tumbled. Products made at 160° C. for 13 days for both methods were isolated and identified to be UZM-50 by XRD. The XRD patterns for both methods were very similar.

Example 30

The product from Example 14 after calcination at 600° C. was extruded as 1/16″ cylinders of 70/30 UZM-50/Al₂O₃ composition and calcined at 550° C. for 3 hours in air.

Example 31

The extruded catalysts of Examples 28-30 were used for the conversion of ethylbenzene. Testing was carried out at 10WHSV. Conversion, pX/X and xylene loss were determined at 260° C., 280° C. and 300° C. The feed comprised 0.9 wt % p-xylene, 64.9 wt % m-xylene, 29.7 wt % o-xylene and 4.3 wt % ethylbenzene. As pX/X is the percentage of p-xylene in the total amount of xylene (ethylbenzene is not a xylene), the pX/X of the feed was 0.94. Equilibrium at these temperatures is about 24. Xylene loss was calculated by summing the total amount of xylenes in the feed and in the product and using the equation XL=100−(Xyl _(prod) /Xyl _(feed))*100 Results obtained from the experiment are reported in Table 4 and in the graph shown as FIG. 7.

TABLE 4 Catalyst Example 28 Example 29 Example 30 Conversion 260° C. 0.45 6.88 1.88 Conversion 280° C. 1.8 11.98 8.63 Conversion 300° C. 8.76 53.38 36.91 Xylene Loss 260° C. 0.12 1.98 0.41 Xylene Loss 280° C. 0.54 4.21 2.63 Xylene Loss 300° C. 3.59 27.14 15.23 pX/X 260° C. 6.26 17.31 18.51 pX/X 280° C. 13.47 19.92 23.08 pX/X 300° C. 20.32 22.87 23.6

Xylene loss increased as ethylbenzene conversion increased; the UZM-50 catalyst of Example 30 (triangles) and the CZB 150 catalyst of Example 28 (diamonds) were on the same xylene loss/ethylbenzene conversion curve as shown by the nearly identical linear fits for these two catalysts (Ex 30 solid fit, Ex 28 hashed fit), whereas the CZB 75 catalyst of Example 29 had much higher xylene loss per unit of ethylbenzene conversion (dashed fit). The example 30 UZM-50 catalyst has the highest pX/X ratio as a function of ethylbenzene conversion (circles) of the catalysts, whereas the Example 28 (x markers) and Example 29 (Greek crosses) catalysts exhibited lower ratios. Therefore, the best catalyst was the UZM-50 catalyst of Example 30 as it combined both beneficial properties.

Example 32 SAXS Fitting of UZM-50 and Beta Zeolite Samples

Small Angle X-ray Scattering (SAXS) is an x-ray based technique which may be used to study and quantify features from 1-100 nm in size. The SAXS experiment probes electron density contrast in a material and as a result, scattering features can arise from a variety of sources including particles, pore structures or density differences in single-phase samples. SAXS profiles were obtained on a RIGAKU SMARTLAB® system operating in transmission mode with a line collimation setup. The SmartLab's rotating anode power makes the measurement extremely sensitive, allowing measurement of dilute or weakly contrasting scatterers. NANO-Solver® provides size distribution functions of nanoscale pore/particles and correlation length functions for materials with density fluctuation based on the non-linear least square curve fitting analysis of X-ray small angle scattering profiles.

Powdered samples were prepared and held between 2 layers of polypropylene film mounted on the Rigaku transmission SAXS sample stage, background correction was performed prior to sample measurements with only 2 layers of the same polypropylene film (0.00025″ thickness). The low angle scattering data were collected from 20 values of 0.12 to 6 degrees with a Cu K-α X-ray beam of wavelength 1.54 Å. The X-rays were generated at 45 kv and 200 mA by rotating anode source for improved intensity. Typical data collection times were on the order of 30 mins. The raw scattering data was analyzed using Rigaku's NANO-SOLVER® software using a split interval of 50 with high slit correction factor.

The data fitted using NANO-Solver® assumed a density contrast between silica or silica/alumina framework (i.e. the crystals) and pore/air. For these samples of interest, all UZM-50 samples required a minimum of 2 distinct size features to fit the observed data. Without wishing to be bound by theory, it is believed that in the UZM-50 samples analyzed here, the smallest size feature observed is due to the crystallite size of the primary UZM-50 crystals. Comparative samples of various beta zeolite preparations were also analyzed. One larger feature was observed >25 nm and a distinct smaller scattering feature consistently in the 6 nm-12 nm size range. The size of the smaller feature fitted for each sample is plotted in FIG. 8 and shown numerically in Table 5.

Unless otherwise noted, materials were analyzed following calcination at 600° C. for 12 hours and ion-exchange with NH₄NO₃ followed by calcination at 500° C. to yield H⁺ form materials.

Example 41 Constraint Index Testing

Constraint Index (CI) is a test describing the relative propensity of a material to crack linear alkanes versus branched alkanes. The competitive cracking of n-hexane versus 3-methylpentane was first described by Haag and coworkers J. Catal. 1981, 67, 218. Additional work to help clarify results of the test have been performed by Zones and Harris Micro. Meso. Mater. 2000, 35-6, 31-36 and Davis and coworkers J. Catal. 2010, 269, 64-70. The CI value may be calculated using Eq. (1) (X denotes the fractional conversion of each species) and thus it is proportional to the observed cracking rate constants of n-hexane (nC6) to 3-methylpentane (3MP).

$\begin{matrix} {{CI} = \frac{\log\left( {1 - {{XnC}\; 6}} \right)}{\log\left( {1 - {X\; 3{MP}}} \right)}} & {{Equation}\mspace{14mu} 1} \end{matrix}$

The UZM-50 catalyst of example 30 was characterized via constraint index testing. Several comparative materials were also tested. Of each catalyst, 5 mL comprising between 2.5 and 3.5 g was loaded into a steel reactor. Conditions were as follows: 5 psig; LHSV=1; liquid feed rate=5 mL/hr; He flow 86 sccm; (HC/He=1:4) using a feed of 50/50 n-hexane/3-methylpentane. Temperatures needed to achieve an overall conversion between 10% and 50% varied from about 420° C. (Example 30 catalyst) to 396° C. (Example 40A catalyst) to between 280 and 300° C. (Examples 40B, 40C, 40D, 40E catalyst) to 267° C. (Example 29 catalyst). Cracked products including propylene were observed from the conversion of hexanes.

As is typically reported, catalysts comprising 8-membered ring pores or small 10-membered-ring zeolite structures such as MTT (example 40A) exhibit CI values greater than 12. Catalysts comprising 10-membered pores of a slightly larger diameter and often with a 3-dimensional pore architecture such as MFI, TUN, IMF, (examples 40B, 40C, 40D, 40E) often exhibit CI values in the range from about 2 to about 12. Large pore zeolites, such as the three-dimensional 12-membered ring pore system of BEA* (Example 29) usually exhibit CI values of less than 1. The UZM-50 catalyst of Example 30 exhibits a CI value of about 1.5. In an embodiment, UZM-50 may have a CI value of from 1 to about 3. In an aspect, the CI value may be greater than 1, or greater than 1.1, or greater than 1.2, or greater than 1.25, or greater than 1.3. In an aspect, the CI value may be less than 3, or less than 2.5, or less than 2, or less than 1.9, or less than 1.8, or less than 1.75.
